Author: hrs Date: Mon Sep 12 23:55:23 2011 New Revision: 225520 URL: http://svn.freebsd.org/changeset/base/225520 Log: - Add ":origin" label to the interface id for resolvconf(8). (r223149) - Add -u option to enable adding :[RA-source-address] to the interface id. (r223149) - s/INET6_ADDRSTRLEN/sizeof(ntopbuf)/ (r223149) - Fix a bug that can prevent -D from being overridden by -d. (r223149) - /-P pidfile/-p pidfile/ for consistency with rtadvd(8). (r223149) - Fix -F flag handling to support receiving RAs even when ip6.forwarding=1.
